574 COLEOPTRRA, 



Crisius Pascoe. Man. N.Z. Coloopt., p. 500. 



4122. Crisius contiguus sp. nov. 



Convex, subovatc, uneven ; piceous, covered witli flat, subrotundate, 

 overlapping squamae, mostly of a greyish-tawny hue, those between the 

 middle of the elytra and the top of the posterior declivity light rufo-fuscous ; 

 legs and antennae fusco-rufous. 



Rostrum moderately broad and arched, subparallel, very slightly nar- 

 rowed near the middle, equalling the thorax in length ; rufescent and 

 closely punctate in front of the antennae, squamose behind them. Thorax 

 a third broader than long, its anterior half abruptly contracted and slightly 

 bicristate at the apex ; the basal portion, in front, with a pair of obvious 

 crests, and a central obtuse carina extending to the base, its punctation 

 quite hidden. Scutellum small or indistinct. Elytra fully double the 

 length of thorax, of the same width as it is at the base, a third broader in 

 the middle, their sides uneven, posterior declivity much narrowed and 

 subvertical ; they are moderately striate-punctate ; the faintly rufescent 

 squamae terminate as a curve just at the commencement of the declivity ; 

 the interstices between the middle and the base though somewhat irregularly 

 elevated are not definitely crested. 



Scape inserted between the middle and the apex, barely reaching the 

 eye ; second joint of funiculus almost double the length of the first, third 

 and fourth suboblong, joints 5-7 transverse, the last rather broader than 

 sixth ; club elongate-oval, its basal joint as long as the remaining two 

 combined. 



Legs normal, femora angulate and dentiform. 



This accords with Crisius with the exception of the narrow elytral base ; 

 in this respect it agrees better with Tychanus, which, however, has a manifest 

 scutellum and medially implanted scape. 



A careful scrutiny of the overlapping squamae and the sublunate termi- 

 nation of the pale ferruginous ones on the after-part of the elytra will lead 

 to its identification. 



Length (rostrum exclusive), 4 mm. ; breadth, nearly 2| mm. 



Glenhope ; 3rd March, 1915. One, found by Mr. T. Hall. 



4123. Crisius eximius sp. nov. 



Subovate, rather narrow, convex, opaque ; rufo-piceous, antennae and 

 tarsi paler ; densely covered with depressed fulvo-ferruginous, and a few 

 suberect greyish squamae, those on the elytra overlapping, the posterior 

 declivity greyish. 



Rostrum as long as thorax, arched, subparallel, obtusely convex along 

 the middle, rather flat and slightly emarginate in front, squamose else- 

 where. Thorax a fifth broader than long, contracted, slightly depressed, 

 and distinctly bicristate in front ; its basal portion with similar crests, the 

 one at each side indistinct ; disc apparently closely punctured, with a slight 

 central ridge behind, its base slightly bisinuate. Scutellum obsolete. Elytra 

 of the same width as thorax at the base, a little wider behind the posterior 

 femora, twice its length, more convex than it is, considerably narrowed 

 and defiexed behind ; apparently narrowly striate -jjunctate, third and fifth 

 interstices a little elevated at the base, all slightly raised near the toj) of the 

 declivity. 



Smaller and narrower than its nearest ally, C. contiguus, the squamosity 

 much brighter, the summit of the posterior declivity without any trace of
